I have the CWM recovery installed, but within Rom manager It's telling me CWM recovery needs to be installed and I need to select a phone. I see the T-Mobile Galaxy S2, but I do not see the ATT Skyrocket. Any ideas?
For some odd reason Im getting "Android is upgrading.. Optimizing X of 62" on every reboot.
Any ideas on this as well?
